Question 1189884: A student wanted to study the ages of couples applying for marriage licenses in his county. He studied a sample of 94 marriage licenses and found that in 65 cases the husband was older than the wife. Do the sample data provide evidence that the husband is usually older than the wife among couples applying for marriage licenses in that county? Explain briefly and justify your answer using the methods studied in this course. Use α= 0.05 as the level of significance. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Ho: husband is not older or same
Ha: husband is older
alpha=0.05 p{reject Ho|Ho true}
critical value z >1.645, z= (p1-0.5)/sqrt(0.5*0.5/n)
z=(0.69-0.50)/sqrt (0.25/94)
=0.19/0.0515
=3.69
reject Ho and accept the alternative in this case.
p-value =0.0002
